hi hi ;
i'm trying to control gpio pin 20 with my smart phone and with event at gpio pin 5 (when the state of the pin 5 changes the gpio pin 20 toggeles )
but my problem is when i add the function gpio_init() the ble stops working .
any help will be appreciated
i'm using nrf51822 s110 sdk 9 pca 20006
